방법: Windows Forms DataGridView 컨트롤에서 내용에 맞게 프로그래밍 방식으로 셀 크기 조정
DataGridView 컨트롤 메서드를 사용하여 잘림 없이 전체 값이 표시되도록 행, 열 및 머리글의 크기를 조정할 수 있습니다. 또한 이러한 메서드를 사용하여 원하는 시기에 DataGridView 요소의 크기를 조정할 수 있습니다. 또는 해당 컨트롤을 구성하여 내용이 변경될 때마다 이러한 요소의 크기를 자동으로 조정할 수 있습니다. 그러나 이 방법은 대형 데이터 집합으로 작업을 수행하거나 데이터가 자주 변경되는 경우에는 비효율적입니다. 자세한 내용은 Windows Forms DataGridView 컨트롤의 크기 조정 옵션을 참조하십시오.
일반적으로 데이터 소스에서 새 데이터를 로드하거나 사용자가 값을 편집했을 때만 DataGridView 요소를 프로그래밍 방식으로 조정하여 해당 내용이 모두 표시되도록 합니다. 이렇게 하면 성능을 최적화는 데 유용하며 사용자가 마우스를 사용하여 행과 열의 크기를 수동으로 조정하도록 허용하는 경우에도 유용합니다.
다음 코드 예제에서는 프로그래밍 방식으로 크기를 조정할 때 사용할 수 있는 옵션을 보여 줍니다.
